When trying to add a BDC to my domain I kept receiving an error stating that the PDC either did not exist or could not be contacted. After some research I realized my DNS server on the PDC was not set up correctly. Its missing the

_msdcs
_sites
_tcp
_udp

folders under the Forward Lookup Zones node with my domain name.

When I installed Active Directory on the PDC I let DCPROMO set up my DNS for me since one didn't exist yet. Anyway, somehow the domain is bearly functioning correctly because I didn't realize this untill I tried to add a BDC 6 months later.

Is there anyway that I can repair the DNS records to the correct state without reinstalling AD.

This is the only Server on my comapanies network so I dont want torisk losing any accounts or the like.

I'd be glad to answer an other questions someone may have if I've left some relevent information out.

Thanx

I ran dcdiag.exe and it returned the following response:

Testing server: Default-First-Site-Name\FS1
Starting test: Connectivity
FS1's server GUID DNS name could not be resolved to an
IP address. Check the DNS server, DHCP, server name, etc
Although the Guid DNS name (673ed7ed-74d5-4b4c-8811-a067bf7d3081._msdcs.headquarters.fabricationdesigns.com) couldn't be
resolved, the server name (fs1.headquarters.fabricationdesigns.com) resolved to the IP address (##.#.##.###) and was
pingable. Check that the IP address is registered correctly with the DNS server.
......................... FS1 failed test Connectivity

***** the # symbols are added by me to hide the IP

I think I solved the Problem I was having. I ran "dcdiag /fix" and that added my SRV records back into my DNS. All seems well now. Hrmm...Curious if I can add that BDC now without any troubles...

wish me luck
